DIFFERENTIAL CAR-WHEEL.

Patented Sept. 1, 1914.

Application filed October 13, 1913. Serial No. 794,790.

Taal/f l'nj/mm it may concern itkuown that I, An'rnun lV. Down, a .r/'en of the United States, residing at Los i r d ungeles, ni the county of Los Angeles, btate 't California, have invented new and useful :Improvements vin Diil'erential Car-lfVheels, Vol" 'which the following 1s a specification.

'lfhis invention relates to a differential .goijistruction for a car wheel or the like; and `the liniention hasas4 its prime object the provision of a simple and ellieient form ol ytlerential wheel for a oar axle, said form inveli ing; a miniu'ium et change in the axle apdivhecl from the present day construction.

Preferably, my invention includes a bearing sleeve which is rotatable on the axle, @aid hearing sleeve 'n.arryingr the wheel; and :i means for holding the bearing sleeve nonies-t longitudinal motion on the axle, nifl hairline' means being covered by the wheel itself. The bearing sleeve is first put upon the. axle and the holding means then pnt in place; the wheel is then forced upon the hearing sleeve in the usual manner. The salu-el eierhangs the holding means so that il. is imiwssille to remove the holding means liili.l tl1e wheel is in place. .The only means by which the Wheel can be removed is to lui-we it nii' the hearing sleeve; and the bearing' sleeve may then 4be removed for reheuvel., otr. My preferred Vform ol holding means 'for the bearing sleeve is a ring serewtl'zreadedupon the axle and held from nn- .screwing by a pin or equivalent. oth the ring;` and the'pin are covered by the wheel itself; itvheing,r impilssible to remove the pin or reach the ring to unseren' it until the heel is forced oil' the bearingl sleeve.

l explain my preferred i'orm of device in the following speeilieation, the saine being illustrated in the :na-,ompnnying,r drawings, in which,

Figure lY is a view showing` a oar axle equipped with my improved differential devire, Fig'. 2 is an enlarged sei-.tion showing my improved differential device with one l'orm of lubricating device. Fig. 3 is a similar sei-tion showing my improved device.`

ln the drawings the numeral desig notes an ordinary car axle having one wheel l! "iggidly mounted thereon in the usual manner. The other wheel l2 I mount on the ear axle in the manner ol my improved devii-e. 'llle car axle has a wheel journal surfare lil over which l put my bearing sleeve Ilil. The hearing sleeve 14 is confined between shoulder 1:7 on the axle and a retailiing ring` lo which is screw-tlneaded at l? onto theaxle. A pin or any equivalent member lS holds va retaining;r ring 1G from un screwing and Forms the end thrust bearing for the bearing sleeve lli The wheel i2 is bored ont to a fort-,ing lit ovel the hearing sleeve lli; and after the bearing sleeve and retaining ringlo are pnt in place, the Wheel is foroed oi, r the hearing sleeve. The wheel ovm-hangs Yfrom the bearing sleeve end covers the retaining ring 16 and prevents the removal of the pin 18. The ring 16 cannot be removed from the axle unless the wheel I2 is :forced oil' the bearing sleeve; and the wheel and bearing lsleeve are freely rotatable on the axle 10.

l may provide means for lubricating the sleeve, including an oil hole Q0, an annular groove 2l, and various holes and grooves 22 and Q3 in the bearing sleeve 14. The amount of lubrication required by the bearing sleeve'is comparatively small; for the amount of rotation of the bearing sleeve upon the axle is comparatively small. I may preferably provide means for inserting a charge of lubricant when the bearii'gi sleeve and wheel are placed upon the axle, said charge being sufficient, for the life of the bearing Sleeve. In Fig. 3 I have shown the bearing sleeve having pockets Q5 in which a suitable solid or semi-solid lubricant may be placed when the sleeve and Wheel are placed upon the axle,

In the construction of my differential wheel l do not Change the usual axle eonstrnelion exi-rpt to out the srrewthreads 17- al the end of the wheel journal surface. 'llnonly change made in the wheel is to bore it out slightly larger `so as to fit over the bearing sleeve 14. 'The wheel an only he removed from the axle in the ordinary manner; that is, by forcing it olil the part over which it fits. Bearing sleeve lll may be made of suitable bearing metal so that it will have a Considerable life. lVhen a bearing sleeve wears out it is only necessary to remove they wheel 'from the sleeve7 remove the sleeve and replace it with a new one, and torce the wheel back into place.

l claim l. A car wheel and axle construction,romprisinfg an axle having a wheel journal surfai-e thereon7 a hearing sleeve around the journal surface, means to sei-nre the bearing sleeve against endwise motion on the axle. und n wheel rigidly mounted on the sleeve und covering the Sleeve securing means to prevent its removal while the Wheel is in plee-1:y on the sleeve.

2A A wheel and axle construction, comprieiug un axle having u Wheel journal srl'aee thereon, u. nearing sleeve revolubleen .he journal surface, u retaining ring Secured on the axle to prevent longitudinalmovenient of the sleeve, and a. Wheel Ii'gidly mounted on the sleeve to revolve therewith ou the axle, the wheel covering the Sleeve retaining,r ring' to prevent iteI removal While the wheel is in place on the sleeve.

3. A wheel und axle construction, Comprising un axle having t wheel journal surlure. thereon, :t hearing sleeve revoluble on the journal surface, a retaining ring screwlhreuded on the axle to prevent longitudinal movement of the bearing sleeve, a pin in the ring und axle to prevent the rili from unserewing, und a Wheel rigidly onnted on the sleeve and extendingl over the ring und pin.

4. A wheel and axle construction, comprising an axle having a wheel journal surface thereon, a ,bearing sleeve revoluble on the journal surface, a, retaining ring screwthreaded on the axle to prevent longitudinal movement of the bearing sleeve, a pin in the ring and axle to prevent the ring from unscrewing, and a Wheel forced upon the sleeve and extending over the ring and pin. l

5. A Wheel and axlevconstruction, eom prising :in axle having a wheel journal surface thereon, u bearing sleeve revoluble on the journal surface, a retaining ring screwthreuded on the axle to prevent longitudinal movement of the bearing sleeve, a pin in the ring and axle to prevent the rin from unsermving, lubricant carrying` poe (ets in the hearing sleeve, and a Wheel forced upon the" sleeve and extending over the ring and the 1n. p ln witness that l claim the foregoing I have hereunto subscribed my name this 6th dey of October, 1913. -f
